HANDLE FOR CUTLERY.

Specification of Letters Patent No. 29,465, dated August 7, 1860.

To all whom it may concern:

Be it known that I, MATTHEW CHAPMAN, of Greenfield, in the county ofFranklin and State of Massachusetts, have invented a new and usefulimprovement in the manufacture of cutlery and tools which have handlesand are provided with a tang and bolster; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, in which- Figure l is a back view of a table knife,constructed according to my invention; Fig. 2, a side view of the same,a portion of the handle being removed or broken away; Fig. 3, atransverse section of the same taken in the plane m, Figs. l and 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

In the manufacture of cutlery and all tools or implements of a superiorclass which have handles, and are'provided with tangs and bolsters, thelatter are most commonly forged on the implement, the blade, bolster,and tang, being all forged from a single bar a transverse section ofwhich is equal in area to that of the bolster,-the blade, if a knife isbeing formed, being drawn out at one side.

of the bolster the tang at the opposite side and the bolster then swagedin proper form. This process of manufacture requires three heats, onefor the formation of each part of the implement and consequentlyconsiderable time and labor is expended.

The object of the within described invention is to obviate thisdifficulty and to this end I make the bolsters separate or detached fromthe other parts, and attach them thereto in a peculiar way, ashereinafter shown and described.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents the blade of a table knife, and B, the tang. The tang isof the fiat form such as are used with handles formed of two parts orwhich nearly divide the handle, the tang being equal in breadth to thehandle and both edges of the former exposed. The blade and tang areforged at once from the same metal bar, a transverse section of which isequal in area to that of a transverse section of the tang. The lattertherefore does not require much labor, the

drawing out of the blade being the principal work. The blade and tangmay be of the usual or any proper form and resemble an ordinary knifewith the exception of the absence of the bolster at the junction of theblade and tang.

The bolsters C, are made separately and may be swaged or cut out inproper form, or they may be cast. The bolsters are formed with alongitudinal slot a in each endsaid slots being equal in width to thethickness of the tangs B.

The tangs B, are slotted at the junction of the blades A, with them.These slots D, are oblong and their ends adjoining the blades areexpanded in V form as shown clearly in Fig. 2. The slots D, are equal inlength to the bolsters C, so that the latter may be insertedlongitudinally in them and then turned at right angles with the'tang andblade, the edges of the tangs at the sides of the slots fitting in theslots a, of the bolster as shown in Fig. 3, the upper surface of thecentral part of the bolster bearing against the upper edge of the slotD.

By this arrangement it will be seen that the bolster is firmly securedto the tang, the former when the handle E is attached bearing snugly onthe end thereof and having the usual appearance. See Fig. 1. Thus itwill be seen that the labor of forging the bolster, with the blade andtang is avoided, and the process of manufacture greatly eX- pedited.

I am aware that bolsters have been made detached from the other parts 0fcutlery and other tools, but so far as I am aware they have been usedwith round tangs and arranged in an entirely different way from thatherein shown and described.

I do not claim therefore broadly and irrespective of the arrangementherein shown and described, the making of the bolsters separately fromthe other parts 0f the cutlery, or other tools, or implements; but

I do claim as new and desire to secure by Letters Patent- The fitting ofthe bolsters C, in the flat tangs B, by means of the slots D, thereinsubstantially, as shown and described.

MATTHEW CHAPMAN.
